Cam & A-Rod Shack Up In Boston!

Things are getting serious now! She’s following him around groupie style!

The Yankees are in Boston to take on the Red Soxs this week, which means the team’s star Alex Rodriguez has some time to enjoy the city between games and practice. Sources say he has been spending most of his off time with his not-so-secret lover Cameron Diaz, who followed A-Rod to Beantown.

Sources claim the couple has been held up in luxury suite at the Liberty Hotel, not even leaving for meals. Instead, they have been enjoying an “incredible time” behind closed doors and ordering a lot of room service.

Naughty, naughty hiding like this!

Whatever could you be doing in there all day long?
